With many roads still blocked by landslides, some Moroccan villagers on Wednesday loaded donkeys with supplies to take to remote areas inaccessible by vehicle, as some earthquake survivors' frustration mounted at the pace of official response.

The 6.8 magnitude quake that struck the High Atlas Mountains late on Friday killed at least 2,901 people and injured 5,530, according to the latest official figures, making it Morocco's deadliest since 1960 and most powerful since at least 1900.

At a roadside, Iydouhmad Mohamed, 42, from the remote High Atlas village of Agndiz, sorted through bundles of relief supplies for his village 12 km away, which could only be reached by donkey. No government officials had reached it yet, he said, days since the quake.
